Issue ID

UUM-105286

Regression

Yes

Global textures fail to render when using an overlay Camera while MSAA is enabled

-

How to reproduce:
1. Open the attached “IN-99388” project
2. Open the “SampleScene”
3. Observe the Game View

Expected result: The sphere is mostly transparent with a water-like effect
Actual result: The sphere is rendered black

Reproducible with: 2023.3.0a19, 6000.0.49f1, 6000.1.4f1, 6000.2.0b1
Not reproducible with: 2023.3.0a18
Could not test with: 2021.3.51f1, 2022.3.62f1, 2023.3.0a17 (missing RenderGraph features)

Reproducible on: Windows 11
Not reproducible on: No other environments tested

Notes:
- Reproducible on Direct3D11, Direct3D12 (however, the user reported crashing on DX12)
- Not reproducible on Vulkan
- Toggling the overlay Camera (UI Camera) off and on temporarily fixes the issue, but it reappears when changing windows, entering play mode, etc., or if MSAA is toggled off and on again in the URP settings
- Enabling MSAA on the global texture fixes the issue (uncomment line 52 in the TransparentGrabPassFeature script)
- 2023.3.0a18 and 2023.3.0a19 show a shader error in the console which might affect reproduction
- 2023.3.0a19 shows the black sphere, but it does not get fixed by toggling the UI Camera (disabling MSAA still makes the issue disappear)
- Also reproducible in Player
